If I had to do it once, I'd brute-force it:

IDL> for a=0.,1.,.1 do for b=0.,1.,.1 do for c=0.,1.,.1 do $
IDL> if a+b+c eq 1. then print,a,b,c

or some such.

If I had to do this many times, I'd consider pre-filling an array
vaguely like this

IDL> r=intarr(11,11,11)
IDL> for i=0,10 do for j=0,10 do for k=0,10 do $
IDL> if i+j+k eq 10 then r[i,j,k]=1

and then later simply looking up r[a*10,b*10,c*10] ...
cordially
